3D Printing as a New Tool for Structural Batteries

Motivated by the request to build shape-conformable, flexible, and structural batteries while maximizing the energy storage and electrochemical performances, 3D printing appears as a revolutionary tool. Battery components such as electrodes, separator, electrolyte, current collectors, and casing can be customized with any shape, enabling the direct introduction of batteries and all electronics within the final three-dimensional object. 3D printing also allows the implementation of complex 3D electrode architectures reported to significantly enhance the power performances. Transitioning from conventional 2D to complex 3D lithium-ion battery architectures will increase the electrochemically active surface area, enhance the lithium ions diffusion paths, and lead to improved specific capacity and power performance.

Design for Sustainability (D4S) and Design for Circularity (D4C) for the automotive industry using state-of-the art sustainability assessment tool

To decarbonize the automotive value chain, innovations that enhance the life cycle and circularity performance of the vehicles are needed at a faster pace. To support this decarbonization goal, ALMA, an EU-sponsored Horizon 2020 project, aims to develop a novel, lightweight structure (at TRL 8) for a battery electric vehicle that has lower environmental impacts compared to conventional design. ALMA project applies a two-level approach: 1) holistic eco-design of the novel vehicle structure and 2) adoption of circular economy principles across the entire vehicle life cycle.
